The initial or startup ATP count is excessive, indicating heavy bacterial growth within the casing. Ileere is a t ub", ue t reduction in the ATP counts on the 5 and 10 minute samples; Iluwever, the counts remain sufficiently high to suggest considerable bacterial activity in tiro mid nttd lowar portions of the wall. The heterotrophic plate counts for the startup and 5-111in10 samples show excessive growth, indicating strong growth and activity among the organisms present. Ilea 10-minute Sample plate count shows a reduction to 50 colony forming units. F,nch sample showed iduntitiealion of a prominent aerobic, slime -forming, organism, with Acromonas speeio detected in the .tart -up and 5-minutes samples and Pseudomonac Specie detected in the 10-minute, Sample. As part of a large overall bacterial population, these organisms would increase, tho propensity Ibr biolilm accumulation in the well system. Ilea strong presence, of anaerobic growth and sulfate reducing bacteria in each sample gives indication of heavy bacterial growth and activity in lower portions of the well where less oxygen is available. Tho high incidence of anaerobic growth can lead to severe blockage al well as coli(urtm release from these areas of licavy biolilm accumulation. Ileere is also putential for anacmbic growth in the gravel pack and nearby formation area around the well, so any rehabilitative Procedure utilized should provide for cleaning of this area. flag microscopic analyses showed the presence of two types of iron oxidizing bacteria, C rtmothrix and Gallionolla. Thcsc organisms oxidize iron, resulting in heavy accumulation of insoluble oxides well in excess of their biolilm production. Ilie iron accumulation is commonly associated with bridging of screen slots and reduced well production. RE -COMMENDATIONS; OMMENl),1TIO1r1S: Overall, the Well shows considerable potential for bio-fouling due to heavy growth of slime forming and iron oxidizing bacteria, as well as ana;-Tobic organisms. Recent coliform positive tesfing would most likely be nssociAtcd with the strong anaerobic growth present in the lower uvoll. In order to best address the coliforni presence, a complete chemical rehabilitation would be recommended over chlorination, as thorough removal of the .anaerobic biomass should Provide a more long-tenn solution with the additional benefit of improving well production. C'hlorinalion tends only to oXI'dize the, surface layers of the polysaccharide biolilm, further complicating the removal of bacteria present_ While the sampling method did clot supply information regarding the gravel pack and aquifer water, a thorough rclt.tbilitllive effort including appropriate chemical treatment and thorough mechanical work should provide sufficient cleaning of this area. If rehabilitation of the well %'-ill tx; Perlbrmed, a cleaning solution consisting of hydrochloric acid and a bio-dispersant product, such As the QC-21 product by Layne, ,Nould be recommended.

As you are aware, we have successfully completed numerous similar rehabilitations in the past. We obtained a sample of the material that had accumulated on your pump column for analysis by our laboratory. We reviewed the videotape of the well casing and screen. We are recommending the following well rehabilitation process based on the infonnation collected and analyzed. • Mobilization and demobilization of men and equipment, lump sum $5,000.00 • Wire brilsh the well casing and screen estimating 50-hours of actual brushing time.

Due to the increased bacteriological problems encountered by Well No. 19, on January 29, 2002, the Community Services and Water Department requested that the funds and the study granted for Well No. 11 be transferred to Well No. 19. Upon the completion of the study, it was determined that Well No. 19 is in need of rehabilitation and the entire pump unit be replaced. In 2001, Layne Christensen rehabilitated Well No. 15 and performed an excellent job. This has been reviewed by the Community Services and Water Department. Based on the experience and familiarity Layne Christensen has acquired with the City's wells, it is hereby recommended that their services be retained to perform the rehabilitation and pump replacement for Well No. 19 at an approximate cost of $258,127.00. Very truly yours, ZC ___- G Z Bruce V. Malkenhorst City Administrator/City Clerk BVM/ng Memo To: Bruce Malkenhorst, City Administrator Fran: Samuel Kevin Wilson, Director of Community Services and Water Date: April 16, 2002 RE: Well 19 Rehabilitation Due to the highly technical nature of well redevelopment, I strongly recommend hiring a consulting firm to perform the rehabilitation of Well 19. City records indicate that Well 19 was constructed in September of 1988. Since this time, it has never experienced any significant mechanical problems, nor has it ever been removed for preventative maintenance purposes. In addition to an exceptional reliability record, Well 19 has been a consistent performer producing in excess of 1300 gallons per minute for over 13 years. Well 19 began experiencing bacteriological problems in January of 2001. From January 2001 to November 2001, Well 19 has tested coliform positive more than twenty times. Since November of 2001, Well 19 has been off-line due to the above -mentioned condition. In attempting to alleviate this, the Water Department has flushed the well, dosed it with large volumes of chlorine, and in November of 2001, had it chemically treated by an outside contractor. None of these measures have alleviated the bacteriological conditions. In January of 2002, Layne Christensen representative, Don Leith, recommended that three samples be taken from Well 19 and sent to their lab located in Ottawa, Kansas for analysis. These samples were taken at the following intervals: startup, 5-minutes, and 10-minutes. The results of these tests indicate a considerable bacterial presence in all three samples. In order to best address the coliform presence, a complete rehabilitation is recommended to provide a long -tern solution to this condition. A detailed report by the lab has been attached for your review. • Page 1 In February of 2002, Layne Christensen was awarded the contract to remove, disassemble inspect, and video log Well 19. Upon inspection by Layne Christensen, it was determined that the entire pump unit was in need of replacement. With the completion of the pump inspection, a video log was performed and confirmed the well was in need of rehabilitation. Over the past month, staff has done extensive research into the rehabilitation process. It was ultimately determined that very few drilling firms possess the technical knowledge to undertake a full-scale rehabilitation project of this magnitude. G: My D==eftVnemosYnemos\WebWM 19 ReFiebi E6w.dw As you are aware, Layne Christensen rehabilitated Well 15 and appeared to do an excellent job. It is highly recommended that the City use Layne to serve as both the consultant and contractor on this project. Layne uses several patented techniques that other firms do not use. In fact, because of these patents, many firms' hire Layne as a subcontractor to expedite various rehabilitation related projects. Below, are just a few of Laynes accomplishments in the field of well rehabilitation: ♦ Layne Christensen has pioneered and pursued many methods of rehabilitation including chemical, Aqua Freed, Bore Blasting and mechanical means. ♦ Layne Christensen has its own technical support group in Layne Christensen GeoSciences. Layne GeoSciences is made up of chemists, microbiologists, geologists, hydrologists and hydrogeologists. This support group uses baseline information and past data to evaluate the wells hydraulic condition. As you are well aware, changing hydraulic conditions may cause lost capacity, water quality changes, taste and odor changes and sand pumping. ♦ Layne Christensen's Fontana office has conducted in excess of 1,000 well rehabilitation's over the past twelve years. As previously discussed, Layne uses many patented rehabilitation techniques. ♦ Anoxic Block: Layne's Patented equipment and procedures are used in gaining negative bacteriological samples with use of inert gases and seals. ♦ Aqua Feed: Controlled injection of liquid CO2, a paten ted process for which Layne Christensen holds the license in Southern California. ♦ Bore -Blasting: A Layne patented process using vibration, gas and water jetting. ♦ Equipment Layne has designed its equipment especially for the rehabilitation wells. Large mixing tanks mounted on 40-foot loboy trailers have been designed with irgection pumps, chemical storage compartments, eyewash and shower installations for safety purposes. ♦ N.P.D.E.S: Layne has designed and built four trailers with mixing, monitoring and injection capabirdies to neutralize all chemicals which may be utilized in well rehabilitation. ♦ Layne has been selected exclusively by many local and international consultants for the sole source of their tried and true methods of well rehabilitation. In a recent discussion with Bert Mason of California Water Service, Mr. Mason informed me that Layne Christensen is used solely to rehabilitate their wells due to their expertise in the field of rehabilitation. Attached you will find the names and addresses of several jurisdictions that have used Layne Christensen to facilitate the rehabilitation of their production wells. Consulting Costs: Layne will analyze all data collected from Well 19 and supply the City with a complete specification list for rehabilitation and additional recommendations for a fee of $110.00 per hour. It is estimated that this work will require 24 man-hours to complete. Total cost: Rehabilitation Costs: The following is an estimate of the associated costs for full well rehabilitation: ♦ Mobilize and demobilize: • Page 2 $2,640.00 $5,000.00 ♦ Wirebrush the well casing estimating 50 hours including wirebrush rental. $11,400.00 ♦ Video log well casing. $450.00 ♦ Move in chemical mixing tank set up and mix batches above ground. Install a dual swab with a 10' spacing and inject the chemical between swabs. During the injection process, swab the chemicals into perforations in a 10' maximum spacing. $51,441.00 ♦ After chemicals have been injected, Layne will install the bore blast and "shock" the chemicals into perforations and gravel pack agitating the space behind the casing as much as possible. $33,500.00 ♦ After the chemicals have had sufficient time to work, Layne will reinstall the dual air swab and jet the water into a Baker Tank and treat it to N.P.0.E.S. standards. ♦ N.P.D.E.S. $19,000.00 ♦ Fumish, install and remove a test pump capable of producing 4500 GPM to redevelop the well to maximum production including a deep suction pipe to maximize the redevelopment process. ♦ Mobilize and demobilize a test engine to operate the test pump including fuel and an operator estimating 40 hours. $12,180.00 ♦ Layne will lower the Ph. to 4 — 4.5 before they start the final chlorination process. The water will be sampled through out the casing with a "thief bailer" to assure the Ph. is at the desired level. After the Ph. adjustment, Layne will chlorinate to 2000 PPM or more. $17,415.00 ♦ Remove the chlorination solution using the airlift method. Discharge solution to be placed into Baker tank. Solution shall be treated to N.P.D.E.S. standards. ♦ Video Log the well casing. Total Rehabilitation Cost: $19,800.00 $450.00 $213,076.00' Price is based on estimated times.

I think it is in the City's best interest to use a drilling firm with vast experience and knowledge to rehabilitate Well 19. Why chance using a drilling firm that does not have a full understanding of the rehabilitation process. This could cost the City additional money, and worst yet, the City could be stuck with a well that produces little or no water. With the City's water demand steadily increasing, it is imperative that Well 19 be rehabilitated to its maximum production capacity. With that said, I would recommend that the City bypass the formal bidding process and contract with Layne Christensen Company to consult and undertake the rehabilitation and pump replacement processes.

The initial or startup A.TP count is excessive, indicaating heavy bacterial growth within the casing. "There is a subsequent reduction in the AI'P counts on the 5 and 10 minute samples', however, the counts icmiain sufficiently high to suggest considerable bacterial activity in the mid nad lower portions of the well. The heterotrophic plate counts for the starttip and 5-ininuto samples show excessive growth, indicating strong growth and activity among the organisms present. 17zc 10-minute sample plate count shows a reduction to 50 colony forming units. Rzwh sample showed identification of a pt'olninent aerobic, slime-fonninb organism, with Acrolnolias specie detected in the start-up and 5-minute4 samples and Pseudomonas specie detected in tlne 10-minute sample. As part of it large overall bacterial population these orbanisins would inerea.w thy; propensity for biofilnn accumulation in the well system, '17tc strong presence of anaerobic growth and sulfate reducing bacteria in each sample gives indication of heavy bacterial growth and activity in lower portions of the well where less oxygen is available.

Thee organisms oxidize iron, resulting in heavy accumulation of insoluble oxides well in excess of their biolilm production. Ilie iron accumulation is colmnionly associated with bridging of screen slots and reduced well production. Overall, the -well shows considerable potential for bio-fouling due to heavy growth of slime tinning and iron oxidising bacIL-ria1, as well as anar.robie organisms. Recent coliform positive testing would most likcly be associated with the strong anaerobic growth present in the lower roll. In order to best address the eolifonn presence, a complete chemical reliabilitation would bu rccotnnnunded over chlorination, as thorough removal of the anaerobic biomass should provide a mom long-teri n solution with the additional benefit of improving well production.

Bacteriological analyses of lie samples submitted from well #19 show a considerable bacterial presence. The initial or startup ATP count is excessive, indicating heavy bacterial growth within tie casing. 'llncre is a sub.", bent reduction in the ATP counts on the 5 and 10 minute sanipias', however, the counts re main sufficiently high to suggest considerable bacterial activity in the mid and ' tower portions of the well. The hcterotrophic plate counts for the startup and 5-minute samples show excessive growth, indicating strong growth and activity among the organisms present. Ilia 10-minute sample plate count shows a reduction to 50 colony forming units. Each sample; showed Wmlilieation of a prominent aerobic, slime -forming- organism, with Acromonas specie detected in the start-up and 5-minutes samples and Pgaudomonas specie detected in ilia 10-minute sainple. As part of a large overall bacterial population, these organisms would increase tho propensity for biofilm accumulation in the well bystern. 'Ilia strong presence of anaerobic growth and sulfate reducing bacteria in each sample gives indication of heavy bacterial t romh and activity in lower portions of the well where less oxygen is available. no high incidence of anaerobic growth can lead to severe blockage; as well as coliform releases from these areas of heavy biofilm accumulation. 11here is also Potential for anaerobic growth in ilia gravel pack and nearby formation area around the well, sn ally rehabilitative procedure utilized should provide for cleaning of this area. 1'11e microscapie analysO-s showed ilia presence of two types of iron oxidizing bacteria, Cn nothrix and Gallionella. Tliese organisms oxidize iron, resulting in heavy accumulation of insoluble o-adzs well in excess of their biofilm production. Ilie iron accumulation is commonly a sociated with bridging of screen slots and reduced well production. 12EMMM ENl).'l'1 IONS: Overall, the weii shows considerable Potential for bio-fouling due to heavy growth of slime firming and iron oxidizing bacterLi, as well as anaexobie organisms. Recent c:oliform positive testing would most likely be associated with the strong anaerobic growth present in the lower well. In order to best address the coliform prc,,,ence, a complete chemical rehabilitation would bo recommended over chlorination, as thorough removal of the .anacrobic biomass should provide a nioro long-tenu solution with the additional benefit of improving well production. Chlorination tends only to oxidize the surface layers of the polysaccharide biofilm, further complicating the removal of bacteria presatit. While the s.tmpling method did not supply information regarding the gravel pack and aquifer water, it thorough relvibilitative effort including appropriate chL inieal treatment and thoroughi mechanical work should provide sufficient cleaning of this area. If rehabilitation of the well %,,ill be l>< 1brined, a cleaning solution consisting of hydrochloric acid and a bio-dispersant product, Such as tic QC-21 product by I.ayno, tiN-ould be recommended.

EXHIBIT B (91 Memo �rBltl�Y tNO��J SgMM To: Bruce Malkenhorst, Administrator From: Samuel Kevin Wilson, Director of Community Services and Water RE: Well 19 - Transfer of Well 11 Funds Date: January 29, 2002 The Water Department is seeking authorization to use funds currently allocated for the removal and disassembly of Well Number 11 and use these funds to have Well 19 disassembled and inspected. Well 19 has tested coliform positive more than twenty times since January of 2001. Since November of 2001 the well has been off-line due to the above mentioned condition. In attempting to alleviate this condition, the Water Department has flushed the well, dosed it with large volumes of chlorine, and in November of 2001, had it chemically treated by an outside contractor. None of these measures have alleviated the bacteriological conditions. In January of 2002, Layne Christensen was contacted and met Water Department officials at Well 19. Layne recommended that three samples be taken and sent to their tab located in Ottawa, Kansas for analysis. These samples were taken at intervals of startup, 5-minutes, and 10-minutes. The results indicate a considerable bacterial presence in all three samples. In order to best address the coliform presence, a complete rehabilitation is recommended to provide a long-term solution to this condition. A detailed report by the lab has been provided for your review. Please advise when time permits.

The Water Department requested quotations for the removal and disassembly of the pumping equipment and video log only. A separate set of RFQ's will be submitted for the repair of the Pump equipment once the extent of wear and the condition of the wellhead has been determined.
